To all whom it may concern:

Be it known that I, Gnonen A. FREDEN- BURGH, a citizen of the United States, residing at the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Processes of Finishing Threads or Yarns from Warp-Beams, of which the following is a specification.

This process relates to finishing yarn or thread as it comes from warp beams; and the objects of this process are to dress, stretch, polish, and more evenly lay the fibers of the yarn or thread after the same has been sized, to increase the product, and to simplify the manner of treating the yarn or thread, whereby the same may be handled in large quantities.

In the accompanying drawings, Figure 1 is a longitudinal section of the front portion of a device for carrying out my process, the view being taken on line of Fig. 6, and showing the direction of movement of the yarn or thread, in the first part or step of the process. Fig. 2 is a partial detail plan of one of the yarn or thread guides of the machine. Fig. 3 is a cross-section taken on line y.g of Fig. 2. Fig. 4 is a continuation View of Fig. 1, showing the relative position of parts to perform the second or last step of the process in finishing the yarn or thread. Fig. 5 is a continuation view of Fig. 4, showing the direction of movement of the yarn or thread as it passes from cloth-covered feed-rolls to be wound on a reel. Fig. 6 is a rear view of the machine. Fig. 7 is a detail view of the gearing-arrangement for the feed-rolls. Fig. 8 is a section taken on line z.-z. of Fig. 7 and, Fig. 9 is a partial plan of another yarn or thread guide of the machine.

thread passes over and in contact upon a wood roller 6, thence over and in contact upon a rod f, and between rings 9, g loosely mounted on said rod, and from said rod the thread passes into the sizing h, contained in a box 6, thence under and in contact between cloth-covered feed-rolls j, j, thereby slightly squeezing and pressing the threads after the sizing thereof, thence over and in contact upon another said rod f and between its rings 9, g, thence over and in contact upon a wood roller k, thence and in contact with a cylindrical brush Z, thence and in contact with a wood roller m, which is octagonal in cross-section, thence over and in contact upon a grooved roller n, thence over and in contact upon another brush Z, thence over and in contact upon another octagonal wood roller m, thence over and in contact upon another rod f and between its rings 9, g, thence again into the sizing h contained inthe second box 2', thence under and in contact between a second pair of cloth-covered feed-rolls j, j, thence over and in contact upon another rod f and between its rings 9, g, thence over and in contact upon another wood roller is, thence under and in contact with another brush Z, thence under and in contact with another octagonal wood roller m, thence over and in contact within the groove of another wood roller 02, thence in contact upon another brush Z, thence over and in contact upon another octagonal wood roller m, thence over and in contact upon another rod and between its rings 9, g, thence under and in contact be tween another pair of cloth-covered feedrolls j, j, thence between pins p which act as thread-guides, thence over and in contact upon a wood roll from whence the yarn or thread feeds on a reel 1. 2

(Z is the main driving-shaft mounted in proper supports (Z (Z of the machine-frame b, and said shaft is driven by a belt-connection (Z with a tight pulley 6Z A pulley Z fast on each shaft Z has a beltconnection Z with a pulley Z, which is keyed on the driving-shaft.

A worm-gear e is made fast at one end of an upright shaft 6 and meshes with a worm a which is keyed on the driving-shaft (Z and at the other end of said shaft 6 is made fast a spiral-gear c which meshes with a spiral-gear a fast on a horizontal shaft 7.

The shaft 7' transmits motion to each contacting pair of feed-rolls j, by means of a gearing-arrangement, as shown in Figs. 7 and 8, and each gearingarrangement for each pair of feed-rolls is provided with a different size change-gear, in order to cause the yarn or thread to become stretched between each set of said rolls. On the shaft f is made fast a spiral-gear f which meshes with a spiral-gear f keyed on a short shaft f The shaft 7, which is supported by a bracket of the machine-frame Z), has a spur gear f made fast thereon and in mesh with a pinion f and said pinion meshes with another pinion f which drives the change-gear f, the latter being keyed on the shaft 7 of the lower feed-roll j.

p The upper feed-roll has short trunnions, as 7' in Fig. 7, which pass through vertical slotted openings 7' formed in the sides of the machine-frame, and a lever 7' is pivoted on a bracket of the latter and adapted to rest upon each trunnion, and a weight j has a wire connection 7' with the free end of each lever, whereby said upper feed-roll is made to bear firmly in contact upon the lower feed-roll and revolve in unison with the latter.

At the rear end of the driving-shaft al is made fast a worm d which meshes with a wornrgear (Z made fast on a shaft (Z extending transverse of the machine, and on the opposite end of said shaft (Z is made fast a pulley (Z having a belt connection with an ordinary friction-drive-pulley (Z which is keyed on the thread-reel-shaft (Z The shaft (Z is mounted in supports (Z (Z of the machine-frame. b, and said shaft has a key (Z made fast thereon and of a length extending between the sides of said frame, in order to fit the spline formed in the hub 7' of the reel '1, whereby the latter may be properly positioned upon said shaft to receive one or more threads, commonly termed ends, as they come finished by this process from the warp beam (1. The reel 1' is held in place by collars (Z which have each a set screw to impinge against said shaft (Z The proper amount of stretch is given to each thread or end by having the first and largest change-gear 7' located on the first set of feed-rolls; the second change-gear f located on the middle set of feed-rolls and of lesser diameter than the first mentioned gear, and the third change-gear 7 located on the lastset of feed-rolls and of lesser diameter than the second mentioned gear.

As the yarn or thread comes from the warp beam it is partly sized, partly brushed, and partly stretched, between the points of location of the first and second change-gears, and from the points of location of the second and third change-gears the thread undergoes a further subjected treatment whereby it becomes more evenly sized, fully stretched, its fibers laid, and the thread polished and fin ished to a high degree of luster by this second step in the process, prior to being wound on the reel.

The sizing used as a dressing for the thread is a cold mixture specially prepared for the treatment of the thread by this process, and a steam pipe 8 is located near the bottom of the machine to keep the temperature up to 110 Fahrenheit, for the purpose of drying the thread before it reaches the reel.

The rollers c, e, 70, m, n and g revolve by frictional contact of the thread. Each roller 11 is provided with a series of grooves, as W, in accordance to the number of threads or ends to be finished by this process, and each groove is formed straight around the peripheral surface of each roller, to keep the threads or ends from contacting with each other.

The rollers m, m are made octagonal in cross-section in order to keep separate each thread or end, and thereby prevent bunches by the latter during its feeding movement.

A series of warp beams and a series of reels may be mounted on the machine, and,

as by practical demonstration, this machine is capable of polishing and finishing as high as 1008 threads or ends in its operation by this process.

Having fully described my invention, what I claim is:

1. The herein described process of finishing a plurality of single threads as they come from one or more warp beams, consisting in smoothing the surface thereof, then passing the same through a cold mixture sizing, then squeezing said threads, then partially stretching the threads, then partially brushing the upper and thereafter the lower half of the threads, then subjecting the same to a second sizing, squeezing, stretching and brushing, thereafter winding up the same, and subjecting the same to heat from a plane beneath and longitudinally of the line of travel of the threads through the entire course of the operation.

2. The herein described process of finishing a plurality of single threads as they come from one or more warp beams, consisting in smoothing the lower sides of the threads, then further smoothing the same on all sides except the top thereof, thence passing the same through a cold sizing mixture, thence pressing the threads, thence polishing the threads upon all sides but one, then polishing the same upon the lower side, then brushing the same upon the upper side, then furthroughout the length of their travel during ther polishing the same upon the upper side the carrying out of the operation. 10
